Read "how to code a secure system": http://catless.ncl.ac.uk/Risks/27.25.html#subj16 . Life offers the challenge of coding a secure self-modifying mind. As the piece above quotes Seneca, "There is a great deal of difference between a person who chooses not to sin and one who doesn't know how".
One answer to your question is another question. What do you want to say now to your 15-year old self?
